Track open nodes in AdvancedDataGrid?

I'm not sure if this is the right place for this question,
but I didn't find anywhere more suitable ...
In beta 1 the AdvancedDataGrid had an openItems attribute
that one could reset after a change to keep the tree in the same
state. Now that attribute is gone and I don't see any other way to
accomplish the same effect.
My use case is that I have an XML document as a hierarchical
data source. I add nodes to it at run-time and need to refresh the
ADG so that the new nodes show up. However on resetting the
datasource the tree closes.
Since the datasource is really the same one (just with new
data) I was previously able to use openItems to reset the tree to
the "open" state it was in before.
Is there a better method for doing this? Or some way to get
the tree to recognize new data without closing?
Many thanks ...
Paul

You can use the openNodes property in
IHierachicalCollectionView.
openItems and openNodes are same. The difference being that
the openNodes property is in IHierarchicalCollectionView instead of
AdvancedDataGrid.
And it was redundant to keep two properties to do the same
thing.
To reset openNodes use -
IHierarchicalCollectionView(adg.dataProvider).openNodes =

How to add an item object as a child for a specified parent node in AdvancedDataGrid in Flex?

Hi,
It's not possible to 'append' a StringItem or a TextField (or any other lcdui.Item object) to a Canvas or GameCanvas. You can only draw lines, draw images, draw text, etc etc, on a Canvas screen. So, you can only 'simulate' the look and feel of a TextField (on a Canvas) by painting it and adding source code for command handling (like key presses). However, this will be quite some work!!
lcdui.Item objects can only be 'appended' to a Form-like Displayable.
Cheers for now,

Its near impossible to get a Advanced datagrid to remember its opened nodes when it has fresh data

Theres a post in
http://www.mail-archive.com/[email protected]/msg85521.html//www.mail-archive.com/[email protected]/msg85521.html
which is basically saying its near impossible to get a Advanced datagrid to remember its opened nodes when it has fresh data
I'm having pretty much the same problem (exept I'm not filtering just getting the latest data from the server)as this guy and have been searching for a solution, heres what he said:
Sun, 02 Mar 2008 08:07:46 -0800
Hello guys,
I'm trying to filter my ADG without success :
I created a GroupingCollection from a flat ArrayCollection.
ADG's dataProvider is GroupingCollection.
First issue : refresh
if I filter the underlaying ArrayCollection, the related
groupingCollection doesn't refresh automatically (bug? feature?)
Actually I menaged to force gc.refresh() with some event( it is
impossible to listen on CollectionEventKind.REFRESH because of
infinite loop ac.refresh => gc.refresh )
Second issue (more important) : openNodes
Ok now that my gc is refreshed, the Tree in the ADG collapses itself
(ok let say that is normal), and I need it to expand all nodes that
were opened before.
I tried to do something like this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
gc.refresh();
myADG.dataProvider.openNodes = openNodes;
and it doesn't works.
next I tried this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
for each( var node : Object in openNodes )
IHierarchicalCollectionView( myADG.dataProvider.openNode( node )
guess what, doesn't work
I'm calling myADG.invalidateList() each time too.
I don't know what to do to achieve this simple task, I'm a bit
disappointed because I expected lot more from the brand new
AdvancedDataGrid and this basic functionality actually seems too hard
to implement.
I still hope I'm wrong and someone can show me the correct solution
Thank you all,
Adnan

Hi,

When creating new track in stereo... track opens in mono in arrange window

Since upgrading to 8.0.2...weird things are happening to previously saved projects. Stereo tracks are opening up mono and affecting following track. When creating new tracks in stereo.... tracks open mono. I don't know if this is due to 8.0.2 but all these freaky things have happening since. Also, when previewing Apple Loops, I can only hear it on one side, but Loops sounds fine once dragged to arrange window. Is this common or is my computer haunted ? Should I call Ghost Busters ? HELP !!! lol

Hi there,
I'm having the same problem as well: creating new tracks results in a mono software instrument, not the usual stereo software instrument. BUT... "Universal Track Mode" is already checked in my Audio prefs. I unchecked & rechecked it, but to no avail... I'm still only getting mono software instruments.
Any other ideas? No changes have been made to my system, and I'm running the latest version of Logic Pro.

Audio track opens in QT, not specified editor

Hmm... Why would an audio track open in QT, not the specified audio editor, when control-clicked and Open in Editor is selected?
Thanks!

This happens when the audio track is part of a video clip. You could set the video editor to the audio application to force it to open whatever application it is is you're trying to open.

Can I track opens and clicks on links in my emails?

I sometimes send emails which contain a number of web links.
Am I able to track:
who opens their email?
which links they click on?
(like I do in Mailchimp)

Thunderbird works to enhance user privacy, not invade it. So no those privacy invading techniques use by web marketers are not supported and where possible actively thwarted.

Tracking opened files and applications as you work

Which log or process on Leopard is tracking when an App or File is opened? I want to be able to monitor when files are opened for certains apps and record the name of files and time opened/closed.
To automate timesheets for people.

It's probably fseventsd, but I don't know of any easy way of tying into it without coding up something or using something designed for that purpose. I have to imagine there's something out there (in the audit space) that will do close to what you want. Maybe something like:

Tree initial state - open node (WD for Java)

Hello,
I have a WebDynpro tree, which I am populating with all the data upfront before displaying it. However, for some reason, when the tree comes up, it is always open, selecting the first leaf (node without children) of the tree.
When navigating away from this view and back, the all nodes are closed.
Anyone know why this is the case, or what settings I must change? I am setting the expanded property correctly on all nodes.
Thanks,
Martin

Martin,
Tree is always follows lead selection of corresponding node. So first part of your problem can be resolved via setting initializeLeadSelection=false for nodes involved.
Next thing that affects behavior is "expanded" property of Tree UI controls. If bound to boolean attrubte, expand/collapse state of Tree can be controlled programatically. Try this if removing lead selection does not solve your second problem.

Assignees don't appear in Issue Tracker Open Issues list?

Open Node in Treee componenet

I want to go to select a particular node of the tree
component when i click
a button.
The tree is having dataProvider XML with 3 levels of nodes
.that is node
inside node inside node type structure
<node>
<node1 attribute="................." >
<node11>
<node111>
<node1111></node1111>
</node111>
</node11>
</node1>
<node2 attribute="................." />
<node3>
<node31>
<node311></node311>
</node31>
</node3>
</node>
The problem is that the node dosent get selected in one go if
its parent
nodes are not open.
I am using myTree.setIsOpen and myTree.selected but the node
doesnt get open
if parebt nodes arenot visible.Someting to do with
getDisplayIndex and index
of nodes.
Can anyone suggets.

How to re-open tree nodes after a refresh to AdvancedDataGrid's GroupingCollection?

Hello,
I have an AdvancedDataGrid, which has as it's dataProvider a
GroupingCollection. The GroupingCollection's source is bound to an
ArrayCollection. Items in the ArrayCollection can be edited.
After a change to the ArrayCollection, I refresh() the
GroupingCollection so it displays properly. Unfortunately, this
collapses the tree of the AdvancedDataGrid, that is, the previously
open nodes are no longer open. I would like to re-open the nodes
after a refresh.
In the code provided, I have attempted to save the nodes
which were open before the refresh, perform the refresh, then
re-expand the nodes with AdvancedDataGrid.expandItem(). But it
didn't work, and I am stumped.
Any ideas on how to expand nodes in the AdvancedDataGrid?
or
Any ideas on how to allow the user to modify a data item,
including fields used as GroupingFields, in an AdvancedDataGrid?

Yes, I try saving the nodes like this:
//save the currently opened items
openArray = new Array();
for each(var obj:Object in advancedDataGrid.openItems)
openArray = openArray.concat(obj);
and then restoring them with the expand function:
//expands the nodes which are passed in as the argument
private var expand:Function = function(array:Array):void
for each(var obj:Object in array)
advancedDataGrid.expandItem(obj, true);
Unfortunately, expandItem just seems to return without doing
anything!

One track doesn't open when opening a frozen session ?

Hi all!
I did a proper and thourough search first, before giong to this question. Didn't find anything about it. And wonder if anyone else has these problems.
Well it opens, but there's no audio track in it... read on.
All of a sudden, apparently out of the blue, when I open a session again, one track seems to be missing and I have to do an Insert audio track again, and freeze it a second time. It's just a trio recording of bass, guitar, drums, so it's no more than a 5 channel session and track lasts less than 10 minutes. It's even the "low" resolution at 16 bit and 44,1 Khz so it can't be a memory issue. Virtually no effects are applied until mastering out, where there's a little limiter on.However, EQ is used individually on each track and it has been frozen.
Having saved and edited a couple of times, and most certainly not have deleted ANY tracks, which you can't do when once frozen.
When I am opening the session again, just ONE track have lost its inserted audio track, and I can't open the "frozen one" again, I have to open the original once more and insert it. It's always the drums overhead left mike which is at channel/track 4. I've been scrutinizing of what I've been doing and most certainly not have undeliberately pushed some hidden delete keys to make it go away.
It's actually quite annoying. Before you ask, yes, I have the latest drivers, the latest upgrades, and a 3,4 ghz CPU Intel, 4gb RAM. Windows XP SP3. It occurs now and then say 3-4 times out of 10. I have just tested it to see if it had anything to do with frozen tracks, so I closed down the whole session with all tracks open - so to speak - and not frozen and then this error/bug hasn't occured at all. At least not in the 10 times I tried it with "unfrozen" tracks. So, a fair guess would be that it occurs while only I have frozen all tracks.
Anyone else experienced this?
/Henke

As I said, read my post "Send me both ses files (no media) via my aatranslator dot com dot au web site". I made no mention of saving "frozen track SES files without any media".
I understand your frustration but I only made an offer to assist.
Now if you want me to have a look at your ses file to see if I can work out what is going on then send it to me without sending any of the media associated with it.
If not I'm happy either way.
BTW
The idea of sending 2 ses files is to compare the one which can't find the frozen track with one that has just been saved and apparently includes the frozen track.

How to make bookmark tree open dynamically when moving in the content?

Intro: When viewing a PDF-file with a bookmark tree, I can unfold(open) nodes in the bookmark tree and make the view window jump to the corresponding destination.
If the bookmark tree is open (unfolded) I can observe a selection mark moving downwards in the bookmark tree as I move down in the content.
Question: Is it possible to make the folded bookmark (outline) tree open dynamically as I move down in the content? I would like to see the bookmark tree unfold automatically and move the highlight to the bookmark (outline) node for the bookmark position nearest to (above) the view point in the content window.

Dave,
thank you for quick and precise answer.
